ffectively one long air stone, bubbler tubing is simply a length of tube which allows air to diffuse through it. Attach to an infusion pump as you would an air stone (using 4mm irrigation fittings) and watch those bubbles go!
Either create a loop of bubbler tubing using a 4mm Tee piece or create an extra long airstone using a 4mm goof plug (to block one end) and a 4mm connector.
